To all whom it may concern.'

Beit known that I, HARVEY L. BRYANT, a citizen` of the UnitedV States, residing in Newark, in the county of Essex and `State of New Jersey, have invented. a new and useful Improvement in Driers, of which 4the following is a specification.

This `invention relates in general to drying apparatus, and in the particular einbodiment illustrated in the drawings, it is shown as utilized in a combined lining and drying machine used in the compound gasket lining of can covers. In this type of gasket lining it is 4essential that the covers and the compoundgasket material deposited in the flanges thereof vs'ha'll be thoroughly dried prior to the application of the covers to can bodies. While my invention is particularly adapted for use in conjunction I with the apparatus employed for this purpose, it will be understood that it has much broader application, and may, from certain aspects, be considered as a general improve-- ment in conveyor and handling meansV for can covers and other like articles.

A principal object of the inventionris the provision of a drying apparatus having conveyor means for simultaneously moving a' plurality of superimposed or aligned covers through a drying chamber.

A further vobjectofthe inventionis the provision in conjunction with an apparatus of this character of automatic feeding mechanism whereby the covers are rapidly and efficiently fed from a lining machine to a plurality of ing chamber. Y

A still further object of the invention is the provision in an apparatus of the foregoing general character of means for discharging tlie dried covers from the appa- ,ratus in `vertically stacked relationship. Still another object of the invention'is the provision of associated cover liningand drying apparatus in which the sameV power means is utilized to operate both the liner discharge and drier' conveyors, and in which .efficient means are provided for transferring the covers from one conveyor to the other,

the entirek mechanism @emprises relatively `one to the other.

guideways provided in the dryfew parts, and being certain, rapid and effective in operation.

YNumerous other objects and advantages of the invention'will beapparent as it is better understood-from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.

Referring to the drawings,

and in them I have shown in outline form y a number of machines 11 for the compound gasket lining of can covers, and a drying apparatus associated therewith and generally indicated by the reference character 12. In the liningmachines 1l the flanges of the can covers are lined with compound gasket material and are delivered therefrom and fed into a discharge conveyor frame 13 by means of a feeding chain 14 which is trained over vertically disposed sprockets 15 and'has protruding therefrom at intervals lugs 16 adapted to move the covers upon a track 1'? and into an appropriate guideway 18 provided in vertical series in the conveyor frame 13, this mechanism being best illus- 46 which rotateswith a power shaft 47. A trated in Fig. 6. The covers are feed indispring- 48 serves to keep said roller in convidually into the separate guideways 18, and tact with said cam and to operate the pusher for this purpose the conveyor frame 13 is head 49 intermittently and in synchronism so constructed as to permit the feeding of With the rotation of the shaft 47. Thus,

the covers-from the different `machines at the covers are tansferred from-the guidevarying levels, the particular guidevvay Ways 18 in the conveyor frame 13 to the which is to receive a cover at a given posi `registering guideways 32 in the drying tion being `provided at the side oppositethe chamber.

A chain conveyor 21 driven of the conveyor 35 and are simultaneously by a sprocket 22 is mounted to travel moved thereby entirely through the U- through a channel 23;in.the-central partof shaped .chamber in Which they are dried. the conveyor frame 13 and has upstanding It will be understood that this last menlugsforflights24thereon which are adapted tioned conveyoriswdrivenby means of .the to propel the cmfersefthrough :the guidesprocket 36 through suitable ygear connection -Ways18.
